On the contribution of the Hall term in small-scale magnetohydrodynamic dynamo
Arijit Halder, Supratik Banerjee, Anando G. Chatterjee +1
A detailed study of small-scale Hall magnetohydrodynamic dynamo has been performed both analytically and numerically. Assuming the magnetic field and the current to be separate fie…
Large eddy simulations using renormalized viscosity
Sumit Vashishtha, Anando Chatterjee, Abhishek Kumar +1
In this paper, we have used renormalized viscosity for performing large eddy simulations (LES) of decaying homogeneous and isotropic turbulence inside a periodic cube on coarse gri…
Energy Spectra and Fluxes in Dissipation Range of Turbulent and Laminar Flows
Mahendra K. Verma, Abhishek Kumar, Praveen Kumar +4
Two well-known turbulence models that describe the energy spectrum in the inertial and dissipative ranges simultaneously are by Pao~(1965) and Pope~(2000). In this paper, we comput…
Dynamics of large-scale quantities in Rayleigh-Bénard convection
Ambrish Pandey, Abhishek Kumar, Anando G. Chatterjee +1
In this paper we estimate the relative strengths of various terms of the Rayleigh-Bénard equations. Based on these estimates and scaling analysis, we derive a general formula for t…
Similarities between 2D and 3D convection for large Prandtl number
Ambrish Pandey, Mahendra K. Verma, Anando G. Chatterjee +1
Using direct numerical simulations of Rayleigh-Bénard convection (RBC), we perform a comparative study of the spectra and fluxes of energy and entropy, and the scaling of large-sca…
Energy Spectrum of Buoyancy-Driven Turbulence
Abhishek Kumar, Anando G. Chatterjee, Mahendra K. Verma
Using high-resolution direct numerical simulation and arguments based on the kinetic energy flux , we demonstrate that for stably stratified flows, the kinetic energy spectrum…
